unraveling stockings and other knittedgoods moistening and ironing silk threads during the unraveling. A further object of my invention l'lS to separate the silk and cotton or other'threads during the process of unraveling and wind ing each upon aseparate drum or spool. I Anotherobject of my invention is to provide a process for reclaiming silk from knitted clippings which. consists of drawing uponf .thethreads .o'f ar5clipping held under a slight tension and; causingthe drum holding the clipping-to belrevolved during the unraveling'of the clipping. a zfurther object" of his "nventio'n is to provide a'drum to" receive tubular clippings and associate with said drum a retarding Weight preferably having mobile characteristics whereby the drum willbe prevented from racing. 1 -A still further object. of *this invention is toprovide a machine which :will' unravel and treat both ordinary hose .clippings? and full fashioned hose i cli'ppings and remove the reinforce thread'during'theWunraveling; i Pr With theseien'ds in view, this invention consists in the "detailsof construction and combination of elements hereinafter set forth and then specifically designatedwby the. claims.

' In order'that those skilledfin" the artto whichthis invention appertains, may understand howto make and use 'thesame, I will describe its construction indetail, referring by numerals "to the acompanying drawings forming which:-' I p I Fig. -1 is an end view jofla machine made in accordance. with myim rovements illus trating thecourse of the treads whenum raveling' ordinary and full fl fashionedf hose clippings.

13 represents a steam chest formed with or secured'toa condensing chamber 14: which latter is supportedby the posts 175 seated upon the arms 9. This steam chest isoblong and set at an angle so thatits. outer surface will serve as anufbning surface and steam is conveyed to the interiorgthereof by apipe 16 leading from anys'uitable source of live steam and in order thatthe waters of con densation may readily pass through said chest'to prevent the undue cooling'there'of, one or more outlets 17 :lead from the'lower' portion of the ;chest to the interiorof the condensing chamber'ld. As the watersof condensation accumulate in the condensing chamber: they are blown cit-through thepipe 18, the flow through said pipe beingcontrolled either bya; hand valve orby an auto matic relief valve. x j

19 represents 'tw'obracket. arms each being supported by theluprights 2 and in 'each of these arms 7 are formed two open bearings 20 and 21 for the receptionojf theosp'indles 22 and 23 respectively-,the spindle 22 carrying the windingdrum 24while the spindle 23 carries the winding drnm25.- Also upon eachof these spindles is secured a friction disc 26,- these friction discs hearing against the friction roll 27 whichjlatter is mounted upon the shaft'29 which is fitted ;to revolve intthe open bearings 30 formedin theoouter ends of the brackets 31,osaid brackets projecting from the uprights 2. Thesh'aft 29 may be revolved from any ,suitablesource'of powerjsoasto givetothe friction r011 27 the proper direction and speed for revolv ing thewinding,drums'24 and 25 whereby the latter'may takeon the threads being unraveled as hereinafter described;

32 are two arms adjustably secured to the legs '1 as indicated at 33 and these arms-are connected by a, guide rod 34 which serves to guide the thread from a certain classof work; L a r .35 are two standards the lower end of each of which is: adapted to fit within sockets -36 formed in the upper ends ofthe uprights 2 and these standardssupport the superstruce threads a certain tension can be uniformally mai tain -there n and Prov si n can be made for multa e usly unra ing thes lk and e ter; readstr ii ,Whieh uch: ba e a e usu ly madei$ c n be eee ip s ed by et ie disease e e t e unrave -is e drum 7 as indicated'at 39 and leadingthe silk thread 40 upward over the feeder 11, the ironing surface of the steam chest and (over the adjustable guide 40 which latter convsists of a bar set in thesockets 41 and maintained in position the screws 42. This thread-thenpasses to the winding drum 2 1:

and as this drum is revolved by friction it will maintain .a uniform pull upon the thread Without at any time exerting a breakwhatever speed it maybe unraveled, as-

suming that the 'drum is normally being revolved ata speed greater than themaximum ofsaid thread; i p

I This arrangement of the friction revolved winding drums and retardeda unraveling drum is essential to the proper handling of the material to be treated since the silk and cotton threads do not unravel at the same rate nor at a fixed ratio, thereforeby=my arrangement. this peculiarity is provide'difor since the unwinding drums 24 and 25 will o revolve at whatever speed is necessarytorece1ve the unraveling threads. w

To unravel and treat what is :knbwnf'in' the trade as full fashion tclip pin i only necessary to suspend'such clipping? indicated at 47 from the hooks 38iand: draw 3 the threads therefrom downward around the guide :34 and then around the unwinding drum 7 after which the threads will be 'theated in the same manneras that described in connection with the threads 40 and 43. Where the machine is constructed of suflicient width both classes of work may be performed at one and the same etiine, but where' it is-desirable to unravel and treat the threadsrfronr .a reinforced hose .clipping", suchfficlippings. are mounted upon'forms 48 andwthe silk thread 49 is led over one of the hooks 38 and down'iunder the guide 34 and then around -the unwind ing, drum 7 after which it-is led upward in the same manner as the thread 40 as before dsci'ibZed In this casethe thread 50 it is o which is being unraveled from the rein forced section 51"is also ledf'upward over one of the iho'oksa38w and downward" and finally attached to the; auxiliary druin. 52 which isof the rsamegeneral constructionas the drum 7 having: anumber of shot or balls 5. re n to g ve the retard ng ct on there to, said drum being loosely mounted upon the shaft 54- having a pulley 5,5 securedto ai haf to hich power m y ob icon yed fro any uiabl sou ce for e olv ng said Pull y ea e-sh ft This arrangemeat will permit the taking up of the reipforced thread 50 as fast as the thread 49' is unraveled but will prevent any undue pull upon the thread 50.

When desired this last described attachment may be so embodied in the machine as to permit the unraveling of either ordinary hose clippings, full fashioned hose clippings or reinforced hose clippings or all three at one and the same time.

Of course I do not wish to be limited to the exact details of construction as herein shown as these may be varied within the limits of the appended claims without departing from the spirit of my invention.

Having thus fully described my invention what I claim as new and useful is 1. A silk reclaiming machine comprising in combination a frame; an unraveling drum; a shaft upon which said drum is mounted; open bearings carried by the frame in which said shaft is journalled; a tray mounted upon the frame; an absorbent strip located in said tray and projected beyond the edge of the same; a steam chest one surface of which is adapted to iron a thread drawn thereover; a winding drum; means to'revolve said drum by friction; a

means for guiding the primary threads I I from the clippings tothe unraveling drum; and means for guidin the reinforcement threads from the clipping totheauxiliary drum.

3. The process of reclaiming silk from a knitted clipping consisting ofplacing said clipping on a drum, winding the thread from said clipping on a suitable device from the drum, the winding of said thread causing the clipping and drum to revolve, and retarding said drum during the revolving thereof.

In testimony whereof, I hereunto affixed my signature.
